Thoughts on the Chain Lock

I think it kinda irks Alyssa
that I do not ever use the chain thingy when locking us in at night.

Call me crazy but ...
(besides the fact that we live on the very top floor)
how does this alleged robber plan to get past dead bolts #1 & 2 ?!!

And call me a cynic but ...
if this aforementioned burgler does get past them,
aren't we pretty much f@%ked then anyways ?!?!?
